Can you add 'global' interrupt as well? While doing so, please make sure the
global_irq related patches are applied and Link up works fine. Those patches are
already in linux-next.

Use GIC_SPI for the parent interrupt specifier.

Sure, let me add global interrupt and have a try. Will also update patch
